This template uses the MIB cbgpPeer2Table, allowing identifying the ASN even when 32-bits. It also allows monitoring IPv6 sessions. The disadvantage of this MIB is that the cbgpPeer2RemoteAddr is an "not-accessible" object, this way, I had to obtain the IP addresses directly from the MIB index structure.
